  cold water fish
     the results of the preliminary study show that so far as cold water fish are concerned, the rise in water temperature can lead to the narrowing of their distribution range, an earlier sex maturation, a reduction in conception and ovulation, a lower survival rate in young fish, which will then bring about the shortening of adult fish’s age, a weight reduction, and the “excaping behavior”.

By making use of the introduced FISH BIOENERGETICS MODEL 2, a dynamic simulation was made of the growth of the main fish species in China’s fishery production (hairtail fish, large yellow croaker and little yellow croaker), and the potential effects of a rise in sea surface temperature caused by climatic change on fishery production was also discussed. Temperature is one of the fundamental and important factors in the living environment of aquatic living things. The sea fish are divided into cold water fish,...

By making use of the introduced FISH BIOENERGETICS MODEL 2, a dynamic simulation was made of the growth of the main fish species in China’s fishery production (hairtail fish, large yellow croaker and little yellow croaker), and the potential effects of a rise in sea surface temperature caused by climatic change on fishery production was also discussed. Temperature is one of the fundamental and important factors in the living environment of aquatic living things. The sea fish are divided into cold water fish, warm water fish, lukewarm water fish and all temperature fish. the change in water temperature has a direct impact on the growing, feeding, spawning, migration, death of the fish and its population change, which, in the end, will affect the quantity, quality and exploitation of fishery resources. the results of the preliminary study show that so far as cold water fish are concerned, the rise in water temperature can lead to the narrowing of their distribution range, an earlier sex maturation, a reduction in conception and ovulation, a lower survival rate in young fish, which will then bring about the shortening of adult fish’s age, a weight reduction, and the “excaping behavior”. All these will cause a decrease in the number of adult fish and fish harvesting volume. As for the warm water fish, lukewarm water fish and all temperature fish, the rise in water temperature might have, to varying degrees, a negative impact on their growth and reproduction. The production and harvesting volume of the main economic species in China’s four sea areas will be lower, ranging from 5% to 15% and 1% to 8%, respectively.

利用引进的 FISH BIOENERGETICS MODEL 2对我国沿海主要鱼种 (带鱼、小黄鱼、大黄鱼 )的生长进行了动态模拟 ,讨论了气候变化引起的海水温度升高对渔业生产的可能影响。水温的变化会直接影响鱼类的生长、摄食、产卵、洄游、死亡等 ,影响鱼类种群的变化 ,并最终影响到渔业资源的数量、质量及其开发利用。从初步研究结果看 ,水温升高有可能使冷水性鱼分布范围缩小 ,性成熟年龄提前 ,减少怀卵排卵量 ,降低幼鱼成活率 ;进而导致成鱼鱼龄缩短 ,体重减轻和出现“逃避行动”;最终造成成鱼数量减少、渔获量下降。而对于暖水性、温水性以及广温性鱼类而言 ,水温升高亦有可能对它们的生长、繁殖有不同程度的负面影响。四大海区主要经济鱼种的产量和渔获量在气候变化后都将有不同程度的降低 ,产量降低幅度在 5%~ 15% ,渔获量降低幅度在 1%~8%。
